1. It has been established that the reduction of the 20-oxo group of steroids to a 20α-hydroxy group, previously described only for a few microorganisms, is carried out by many actinomycetes.

2. A correlation has been found between the action of the actinomycetes studied on progesterone and the steric, directivity of the reduction of 17α-hydroxyprogesterone by these cultures.
